.To alii whom may concern f l f y Be it known that l, GRAY l. "Montese,a citizen' of tlie United States residing at Chicago, in the county ofCook and State of illinois, have' invented certain new and use ful'improvements in l'elumidityontrolling Meciiaiiism ttor Drying-Rooms.)oi which the following ie a specifioationv This invention relates 'to adevice for automatically controlling the admission of Steam to a dryingroom for maintaining a conetant degree of humidity in tlie atmosphere ofthe room in the drying oi' certain articles, as, im:

instance, variiishcd or enameled Ware, it is desirable to maintain apredetermined degree of humidity in the room in order to Secure the bestresults. it has been found that if the atmosphere is allowed to becometoo dry there is a tendency to dry and harden the exterior surface oithe varnish or enaroel before tiie underlying coats oi? varnish orenamel are thoroughly dry and hardened, which imperfect drying is termedcase hardening, and is very objectionable from every standpoint. liyproper regula,u

tion of tile humidity in tl'ierooni, this and other objectionableresults [may be avoided.

The object of the present invention is to provide means forautomatically admitting or restricting the adinieeion'of the steamutilized for liamidiiying gnr'poeee, in euch a manner as to maintain thedeeired degree et humidity in the room.

These features arecommon in instruments oi 'tliieclaee7 and need not bey furtherdescribed. in utilizing," theI humidity gage for the purpoa'es oi thepresent invention, a circuit? Wire 6 ie provided, which connected withthe manually adjustable hand or pointer 5; and a, eiiiiilar Wire 7 leads:from the automatically adjust-able hand or pointer 4,4 the parte beingsuitably insuiated so that no circuit can be established until theautomatically adjustable hand or pointer llas moved to a positioncoincident with 'that of the manually adjustable hand ,or pointer, atwhich time a Contact will be eiiected and the circuit established. Thecircuit Wires 6 and 7 lead to and connect with a pair oi" binding poetsS on the end of an electro# iagnet i?, having a soft iron corel()prefer@4 ably incloeed in a sheath or easing adapt- -ed to protect themagnet from the action oi preifeiaoiy iorined of al material Wiiicii`will to the attraction oi' the magnet I be eene and me saine timeimpervious to tlie aetion of the steam. The part" aile preferablyarranged eo that tiie flap val 'e will ialloy avity, aeeieted icy themagnetic influence, to close the dieeliarge of the nozzle against thedischarge of the Steam, but Wili rise mrder a low steam pressure whenthe magnetic attraction is removed.

in operation, a'iter the desired humidity for the room has beendetermined uoony the manually adjustable hand or pointer Wiil be movedto the desired degree, as, for instante, 250, and the Steam will beadmitted. to the room. the aatooziatically adjustaoie handorpoiater willinoye until it comeeto a position co incident with thatol12 the manuallyadjust-- able hand oi pointer, at which' time a con- Ae the humidity.increases, i

tact will be formed and the circuit closed, which serves to energize themagnet, and

with the magnet energized the flap valve will be drawn down against theslight steam pressure and the nozzle closed against the admission ofaddition'alv steam. So long as the humidity remains at the desireddegree, the circuit will'be maintained, but when the humidity againbegins to fall, the circuit will be broken and the magnet denergized,allowing the flap valve to rise under the steam pressure, which willadmit additional steam until the humidity in the room has been vagainraised to the desired point. The parts will thus be maintained inpractical equilibrium during the drying operation, with the humiditypractically constant at all times.

ln some cases it may be desirable to vary the humidity in the roomduring the diiferent stages in the drying operation, but, of course,this can be readily effected by turning the manually operated hand orpointer to diiierent positionsl as occasion may require. The device isextremely simple in construction and may readily be employed with anyone of several well knoivnforms of humidity gages which canbc readilyadapted to the requirements of the present invention.

Although the invention has been defined as applicable tor use in dryingrooms, it is obvious that it may be employed in living rooms, storerooms, Work rooms or the like, or under any other conditions where it isdesirable to regulate and maintain constant degrees of humidity. It isalso evident that some humidifying agent other than steam may be used ifdesired.
